What formula is used to calculate fuel consumption?

The formula for calculating fuel consumption measures how effectively a vehicle uses fuel relative to the distance it travels. The correct formula involves taking the amount of fuel used, multiplying it by 100, and then dividing by the distance travelled. This gives a measure of fuel efficiency expressed in terms of fuel consumed per unit of distance, usually in terms of liters per 100 kilometers.

Using this formula allows you to understand how much fuel is consumed for every 100 kilometers driven, which is a standard way to assess vehicle efficiency. It provides a clear perspective on fuel consumption, making it easier to compare different vehicles or assess changes in driving habits.

The other options do not accurately reflect how fuel consumption is typically calculated. They either reverse the relationship or combine fuel and distance in ways that don't provide a meaningful assessment of fuel efficiency.
